Tuple<T1, T2, T3, T4, T5>.ToString Method

Returns a string that represents the value of this Tuple<T1, T2, T3, T4, T5> instance.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public override string ToString()

Return Value

Type: System.String
The string representation of this Tuple<T1, T2, T3, T4, T5> object.

The string returned by this method takes the form (Item1, Item2, Item3, Item4, Item5), where Item1, Item2, Item3, Item4, and Item5 represent the values of the Item1, Item2, Item3, Item4, and Item5 properties, respectively. If any of the property values is null, it is represented as String.Empty.

The following example illustrates the ToString method. It displays an array of 5-tuple objects that contain the name of a state in the United States, its population in 1990 and 2000, its population change in this 10-year period, and the annual rate of population change.


using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Define array of tuples reflecting population change by state, 1990-2000.
      Tuple<string, int, int, int, double>[] populationChanges = 
           { Tuple.Create("California", 29760021, 33871648, 4111627, 13.8), 
             Tuple.Create("Illinois", 11430602, 12419293, 988691, 8.6), 
             Tuple.Create("Washington", 4866692, 5894121, 1027429, 21.1) };
      // Display each tuple.
      foreach (var item in populationChanges)
         outputBlock.Text += item.ToString() + "\n";
   }
}
// The example displays the following output:
//       (California, 29760021, 33871648, 4111627, 13.8)
//       (Illinois, 11430602, 12419293, 988691, 8.6)
//       (Washington, 4866692, 5894121, 1027429, 21.1)
